Carbon dioxide (CO2) is a by product of a chemical conversion process used in the production of clinker, a component of cement, in which limestone (CaCO3) is converted to lime (CaO). CO2 is also emitted during cement production by fossil fuel combustion and is accounted for elsewhere.
What is the Process of Making Concrete?. Before it can become a driveway, patio or foundation, concrete must be combined from a mixture of sand, aggregate or gravel, Portland cement and water. Once these ingredients are mixed together, the wet concrete product is poured into a form that serves as a mold.
Manufacturing Portland Cement. The basic ingredients of both the dry and wet processes are the same. By mass, lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore. Since limestone is the main component,...
